Scott Posted August 21, 2011 Share Posted August 21, 2011 Is it important to have the water going through the ICV? I can't see any reason why it would need it but don't want to miss anything. Same question for the throttle body. I'd rather get rid of as much as I can. They seem very short and don't seem to serve much puprose other than to split up the connection through the manifold side of the engine. Thanks.

hodge Posted August 21, 2011 Share Posted August 21, 2011 All it's for is to stop the TB and ICV from freezing in cold weather. There not needed mate. It's less for the water to flow so it's better for the engine. Quote Link to comment Share on other sites More sharing options...

What do I do with the hard pipe that goes underneath the car? Where is it going to? Can I just block it off. Thanks again mate Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted August 21, 2011 Share Posted August 21, 2011 Just to add, when I got my car, it had the water pipes on the ICV cut off and the feed pipe looped back on itself. Quote Link to comment Share on other sites More sharing options...

Just bend it down to vent under the car or personally I'd just trace back to the tank, remove the hard pipe and run a pipe out the back under the car with a non-return valve on the end.

Scott Posted August 21, 2011 Author Share Posted August 21, 2011 Is it best not to cap it off then? I was thinking of cutting it down nearer the bottom of the firewall (so that it's hidden) and then capping it so that crap doesn't get in?

hodge Posted August 21, 2011 Share Posted August 21, 2011 Don't cap it off, fit a non-return valve so it can vent but nothing can get back it. Quote Link to comment Share on other sites More sharing options...
Scott Posted August 21, 2011 Author Share Posted August 21, 2011 What type of valve should I use John? Would a fuel one way valve suffice or should I be looking at something like an aquarium one? http://www.ebay.co.uk/itm/10-Non-Return-One-Way-Check-Valve-Co2-Aquarium-Air-Pump-/280714997477?pt=UK_Pet_Supplies_Fish&hash=item415beaeee5 http://www.lkperformance.co.uk/One-Way_Fuel_Valves/FSEOne-Way_Valve_6mm_Small_Type/219028 Cheers Quote Link to comment Share on other sites More sharing options...
hodge Posted August 22, 2011 Share Posted August 22, 2011 Id use the 1 way fuel valve Scotty. Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 23, 2011 Share Posted August 23, 2011 Be wary about removing the water heating to the throttle valve, especially living ooop north! In very cold humid weather it's all too easy for throttle plates to freeze open, and you may find yourself in a mess. They make very little difference to the intake air temp, they just stop condensates freezing up. Quote Link to comment Share on other sites More sharing options...

In very cold humid weather it's all too easy for throttle plates to freeze open, and you may find yourself in a mess. They make very little difference to the intake air temp, they just stop condensates freezing up. I was thinking that but I then wondered if the aftermarket TBs had central heating or not? My car is always garaged so I would be surprised if it froze. I always let my car heat up in the winter also so I doubt the engine bay temps would be low enough to allow the tb to freeze. I'll still keep it under advisement though, if I know it's potentially an issue I can take the above measures to make sure the tb is toasty.

dandan Posted August 23, 2011 Share Posted August 23, 2011 It's for when you are driving Scott - stops the throttle freezing in an open position Quote Link to comment Share on other sites More sharing options...
David P Posted August 23, 2011 Share Posted August 23, 2011 I ran my N/A without a hot water feed right through last winters ice-age without issue and the induction temps are lower than a T.T. Quote Link to comment Share on other sites More sharing options...
dandan Posted August 23, 2011 Share Posted August 23, 2011 The throttle body in an NA is in quite a cosy spot anyway and the humidity in icy weather will be very low as the cold air can't hold much water... Quote Link to comment Share on other sites More sharing options...
dandan Posted August 23, 2011 Share Posted August 23, 2011 I'm not saying it can't be removed though, I think mine is bypassed Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 23, 2011 Share Posted August 23, 2011 They tend to freeze at sustained part throttle as the depression across them drops the air temp even more, and any moisture in the air condenses and freezes. Quote Link to comment Share on other sites More sharing options...
